Embodiment 1

[0037] A method for judging the state of a station AC network topology node, comprising the steps of:

[0038] Step 1. First, use the drawing tool visio software to draw the topology of the station power AC network, such as figure 1 As shown, the switch data file is generated according to the topology structure. The switch data file includes: switch name, type, switch first node, switch end node, switch status and detailed description;

[0039] The file format is shown in Table 1 below:

[0040] Table 1, Switch Data File Table

[0041]

[0042] The name of the switch in the above table is a self-defined name, and no repeated switch name can appear; the type uses ZB to indicate the station power switch; the first node of the switch and the last node of the switch are the node numbers of the first and last ends of each switch; the opening and closing state uses 0 and 1 Indicates that 0 indicates the closed state, and 1 indicates the open state; the detailed description is t...

Embodiment 2

[0064] A device for judging the state of a switching node in an AC network topology for a station, comprising:

[0065] The search set generation module is used to traverse the pre-generated switch data file, record the switch numbers between adjacent nodes and adjacent nodes, and mark the terminal nodes to form a search set; the switch data file includes: switch name, switch type , switch first node, switch end node, switch status and detailed description;

[0066] The node state judgment module, when the switch state or the power state changes, traverses the terminal nodes in the search set in turn, judges the state of the terminal node and its adjacent nodes, and obtains the charged state of all nodes; the terminal node is none Switch end nodes of adjacent switches.

[0067] Further, the method for generating the switch data file is as follows: drawing the topology of the station power AC network, exporting the topology data, generating the switch data file, and associatin...

Abstract

The invention discloses a station alternating current network topology switch node state determination method and device, and the method comprises the steps: traversing a pre-generated switch data file, recording switching numbers between adjacent nodes, marking terminal nodes, and forming a search set, wherein the switch data file comprises a switch name, a switch type, a switch head node, a switch tail node, an on-off state and detailed description; when the on-off state or the power state changes, sequentially traversing the terminal nodes in the search set, and judging the states of the terminal nodes and the adjacent nodes to obtain the electrified states of all the nodes, wherein the terminal node is a switch tail node without an adjacent switch. The method and device can improve thejudgment speed and precision of the state of the switch node.

Description

technical field [0001] The invention relates to the technical field of power system simulation, in particular to a method and device for judging the state of a switching node of an AC network topology for a station. Background technique [0002] When the substation is in normal operation, the substation AC system directly provides cooling, energy storage, tide driving, lighting and other power supplies for the main equipment of the substation. And as one of the power sources of the DC system. Whether the AC power used by the station is reliable directly affects the long-term effective operation of the AC-DC system. [0003] In the substation 3D simulation training system, the station AC system simulation also realizes the same function. The rapidity, correctness and stability of the state calculation of the network topology switch nodes of the substation AC system are crucial to the fast, correct and stable operation of the 3D simulation training system of the entire subst...
